Sport Relief 2012, BBC One & Two, preview

The celebrities are out in force for Comic Relief’s sporty counterpart, hosted by a line-up of such perennial favourites as Gary Lineker, Davina McCall and Dermot O’Leary. David Walliams will be looking smug about having swum the Thames last year, as will fellow comedian John Bishop, who cycled, rowed and ran from Paris to London, and TV presenter Helen Skelton, who skied and biked to the South Pole. Pity the poor celebrity who has to top that next year.

Meanwhile the BBC does what it does best, rustling up stars for spoof editions of hit shows. Kate Moss and Stella McCartney crop up alongside Jennifer Saunders and Joanna Lumley in Absolutely Fabulous, while Strictly finalists Harry Judd and Chelsee Healey have a rematch, but this time they’re underwater. There’s also the alarming prospect of Benidorm meets Britain’s Got Talent, starring Simon Cowell, Alesha Dixon, and Ant and Dec. As ever, the comedy is interspersed with well-judged films about how the money is spent. Earlier in the day, CBBC gives over its whole slot to a celebrity-filled Sport Relief warm-up (BBC One, 3.05pm), and the fun continues into the night on BBC One.
